During the Tang Dynasty, Japanese monks studied in Tiantai Mountain, Zhejiang Province. After returning home, they brought Tiantai Sect not only to Japan, but also to Hiei Mountain in Kyoto. Later, Shang Rong also studied Buddhism and tea art in Tiantai Mountain, and wrote the famous "Eating Tea for Health", which recorded the tea-making techniques and tea-ordering methods popular in Jiangsu and Zhejiang during the Southern Song Dynasty, and was known as the "tea ancestor" of Japan. After that, monks studying abroad brought back camellia seeds and planted them in Shizuoka Prefecture, their hometown, and the tea wind began to spread.
